题
我是Symfony的新手。我决定使用Symfony版本2移动轮子。
在我的用户表格中:
- 我想在数据库中验证电子邮件的唯一性。
- 我还想使用确认密码字段验证密码。
- 我可以在Symfony2文档中找到任何帮助。
解决方案
这些东西也花了我一段时间来追踪,所以这就是我想到的。老实说,我不确定用户实体的Getroles()方法,但这只是我的测试设置。诸如此类的上下文项目仅是为了清晰的。
以下是一些有用的链接以进行进一步阅读:
我将所有这些设置为确保它作为安全性的用户提供工作,因为我认为您可能正在这样做。我还认为您将电子邮件用作用户名,但您不必这样做。您可以创建一个单独的用户名字段并使用它。看 安全 了解更多信息。
实体(仅重要的部分;可自动化的getters/setters):

use Symfony\Component\Form\FormBuilder;
class UserType extends AbstractType {
public function buildForm(FormBuilder $builder, array $options) {
$builder->add('email');

one field in the model and they both must match */

$form = $this->createForm(new UserType(), $user);

$form->bindRequest($request);
if ($form->isValid()) {
// encode the password
$factory = $this->get('security.encoder_factory');

$password = $encoder->encodePassword($user->getPassword(), $user->getSalt());
$user->setPassword($password);
$em = $this->getDoctrine()->getEntityManager();
$em->persist($user);
$em->flush();

其他提示
查看 http://github.com/friendsofsymfony 有一个具有该功能的UserBundle。您也可以检查 http://blog.bearwoods.com 有关于添加自定义字段,约束和验证器的博客文章。
如果您仍在遇到麻烦的情况下,人们通常会在FreeNode Network上的#Symfony-Dev上对IRC有帮助和友好,那么Thoose Resources应该让您开始正确的道路。在FreeNoce上,还有一个通用频道#symfony,您可以在其中询问有关如何使用#Symfony-Dev在Symfony2 Core开发的地方的问题。
希望这将有助于您继续进行项目。
我认为创建自定义验证器时需要注意的主要内容是在getTargets()方法中指定的常数。
如果您更改
self::PROPERTY_CONSTRAINT
至:
self::CLASS_CONSTRAINT
您应该能够访问实体的所有属性,而不仅仅是一个属性。
注意:如果您使用注释来定义约束,现在需要移动注释,该注释将您的验证器定义到类的顶部,因为它现在适用于整个实体,而不仅仅是单个属性。
我已经完成了 http://symfony.com/doc/2.0/book/validation.html
我的配置:
validator.debit_card:
class: My\Validator\Constraints\DebitCardValidator
tags:
- { name: validator.constraint_validator, alias: debit_card }
试图与它一起使用
@assert:DebitCard
@assert:debitCard
@assert:debit_card
但是它没有触发吗?
来自数据库的唯一电子邮件
验证
DashboardArticleBundleEntityArticle: constraints: #- SymfonyBridgeDoctrineValidatorConstraintsUniqueEntity: senderEmail - SymfonyBridgeDoctrineValidatorConstraintsUniqueEntity: { fields: senderEmail, message: This email already exist }
使用确认密码的密码
$builder->add('password', 'repeated', array(
'first_name' => 'password',
'second_name' => 'confirm',
'type' => 'password',
'required' => false,
));
